The most notable changes to the 2016 A6 sedan occur under the hood. While engine sizes are unchanged, there are healthy increases in power all around. The base 2.0T now pumps out 252 horsepower and 273 lb-ft of torque from its 2.0-litre turbocharged four-cylinder engine. The 3.0T continues with a supercharged 3.0L V6, but is now rated at 333 hp and 325 lb-ft of torque. The diesel-powered TDI carries over for 2016, producing 240 hp and 428 lb-ft of torque. Audi’s Quattro all-wheel-drive system is standard. The rest of the changes for 2016 are cosmetic — the sheet metal sees sharper lines and a sportier look. Changes were made to the grille, headlights, air inlets, bumpers, side sills, rear lights and tailpipes. Audi optionally offers headlights with LED technology or Matrix LED technology, combined with dynamic turn signals.
